Embodiment
Please refer to Fig. 3 and Fig. 4, it shows respectively manufacturing process calcspar and the schematic diagram of horn vibrating reed.As shown in the figure, first provide fiber cloth material (step S1).With reference to figure 5, it demonstrates the partial schematic diagram of fiber cloth material 100, in figure, demonstrating fiber cloth material 100 is mainly by warp thread 11 and weft yarn 12 fabric forming that weaves, warp thread 11 and weft yarn 12 fibre composition used can be polyester fiber, cotton fiber, acryl fiber, silk fiber, PEN (PEN), benzamide fiber (Aramid), bamboo fiber etc., but non-ly only limits to this.
At this, optionally discharge process (step S6) is carried out in fiber cloth material 100 surfaces, to improve the surface energy (surface tension) on fiber cloth material surface.Above-mentioned discharge process can be electricity slurry discharge process or Corona discharge Treatment.
Electric slurry is for example processed, according to passing into different gas electric pulp (argon gas, oxygen, nitrogen and fluoro-gas), can make surface for example, with different functional groups: oxygen plasma processing can promote the surface energy of fiber cloth material; And on the contrary, fluoro-gas electricity slurry can reduce the surface energy of fiber cloth material, can optionally apply.In addition, can for example,, by passing into inert gas electricity slurry (argon gas), fiber cloth material be produced crosslinked.
Similarly, corona treatment (Corona) is also that a kind of " electric shock " processed, and it can make fiber cloth material surface have higher tack.The generation of Corona is to utilize high voltage high frequency, is respectively ground connection and produces electric shock with luring electric air nozzle, does not have electric current to pass through, until voltage is up to 9000～/ 5000 volts/square centimeter between them.Afterwards, electric shock molecule sprays from air nozzle, accelerates to rush at positive pole with high-octane free electron, and corona corona treatment is exactly intensive by this and high-energy sprays the effect that ion produces.Then these ions are by electric shock with penetrate into its molecular structure of surface breakdown of fiber cloth material, and then by processed surface molecular oxidation and polarization, by ion electric shock erosion surface, to such an extent as to increase the adhesive ability on fiber cloth material surface.
With reference to figure 6A and Fig. 6 B, it shows respectively the surface tension schematic diagram of horn vibrating reed before and after discharge process.As shown in the figure, when drop is on the surface of solids, form film or liquid pearl, representing the affinity power of liquid and solid, can be referred to as again to soak (Wetting) behavior.When liquid is at the wetness degree of the surface of solids, can determine with contact angle for the surface tension between liquid and solid, surface, wherein, the SI of surface tension unit is made as N/m=kg/sec
2=J/m
2; CGS is made as dynes (dyne)/cm=g/sec
2=ergs (ear lattice)/cm
2.
Contact angle (Contact Angle, θ) can (Surface Energy) be the index of weighing the hydrophilic, hydrophobic property of material itself with surface, and contact angle (θ) refers to the angle of the surface of solids and liquid surface.The theoretical test value of contact angle is 0～180 degree, and in the time that θ < 0 spends, surface is completely moistening, and in the time that θ > 180 spends, surface is not exclusively moistening.When θ=1, the attraction of Ze Ye ╱ solid is greater than the attraction between liquid.The size of contact angle is relevant with surperficial hydrophobicity, and when the contact angle of material and water droplet is larger, hydrophobicity is higher; The contact angle of material and water droplet is less, and hydrophily is higher.In the time that surface can be larger, surface is can adsorbable liquid (drop) ability just larger, and liquid adsorption area is also larger, causes surface contact angle less.
Contact angle and the surperficial hydrophilic or hydrophobic ability of material inhibition that can concern, as shown in Fig. 6 A, at large (low surface tension/low-surface-energy) of contact angle carrying out before discharge process, and Fig. 6 B is after discharge process, its fiber surface is large (high surface tension/high surface energy) of its contact angle after upgrading, with horn vibrating reed, its surface can be preferably between 20-60 dyne, contact angle between 0-90 degree, can effectively promote by this combination of fiber cloth material surface and resin, glue line material or other functional aid.
Then, fiber cloth material is impregnated in to liquid resin (step S2), makes fiber cloth material absorb resin and there is certain hardness, then and by the fiber cloth material containing after resin pickup dry.Selecting of resin material can be one of them or its combination of phenolic resins, epoxy resin, mylar, or other has the macromolecule resin material of thermosetting characteristic, is not limited only to this.Under drying regime, can again optionally discharge process (step S6) be carried out in fiber cloth material surface, its mode and principle are same as above, are not repeated.
One glue-line (step S3) is set on fiber cloth material, can be by the mode of screen painting or alternate manner coated glue layer material, and glue line material can be rubber, silica gel or other macromolecule glue material, then and by the fiber cloth material after coated glue layer material dry.Under drying regime, also can again optionally discharge process (step S6) be carried out in fiber cloth material surface, its mode and principle are same as above, are not repeated.
With the temperature heating impression shaping (step S4) of 200-230 degree.So far, multiple horn vibrating reeds 200 without cutting on overall cloth material, have been formed.Resin bed 23, glue-line 24 that warp thread 21, weft yarn 22 and the thermosetting of horn vibrating reed 200 form are intactly configured as an overall structure (as Fig. 8 A).
Then the fiber cloth material being shaped can be cut to (step S5), also can form central through hole (not shown) for each horn vibrating reed in this step, and cut unnecessary fabric to obtain final horn vibrating reed.Complete after finished product, can again optionally discharge process (step S6) be carried out in fiber cloth material surface, its mode and principle are same as above, are not repeated.
The horn vibrating reed processing procedure of the present embodiment can be through discharge process once or for several times, and this discharge process step can horn vibrating reed form before or after any drying regime under, before or after being included in fiber cloth material impregnation resin steps, arrange after glue-line and form in any one or more step after horn vibrating reed, one or many discharge process is carried out in its surface, to improve its surperficial roughness and surperficial energy.The benefit of multiple discharge processing is, chemical assistant, the macromolecule resin material that can add for different step institute wish individually, help the absorption of fiber cloth material to these materials, only give single step of releasing electric treatment when initial, the effect of multiple discharge processing is better, but expends time-histories and operating cost.
Object and the advantage of discharge process are numerous, are to help engaging of horn vibrating reed and other horn component in this topmost application.As shown in Fig. 7 A and Fig. 7 B, it demonstrates respectively partial discharge horn vibrating reed after treatment and the then position with horn component thereof.Lifting at the horn vibrating reed after discharge process due to its surface roughness and surface energy, comprise overall discharge process or the partial discharge processing for the key position of following, to increase solid 4 and horn vibrating reed 200 and to follow the Bonding strength between target.Partial discharge processing can be reached by shielding or alternate manner are set, or can for wish strengthen that the region of discharge process gives repeatedly or the discharge process of higher-strength, can reach equally identical object.
Example as shown in Figure 7 A, in cloth surface, the cyclic position at inner edge place, contiguous center carries out discharge process in the above described manner, to form one first coarse doping region 233, or carry out discharge process at the cyclic position at vicinity outer rim place, cloth surface, to form one second coarse doping region 234, alternatively or possess and all can simultaneously.These two positions are respectively the then point of horn vibrating reed central through hole inner edge and voice coil loudspeaker voice coil and the then point of horn vibrating reed outer rim and chase, mainly that horn vibrating reed is in the time shaking along with voice coil loudspeaker voice coil, the stressed position of topmost key, also be the most easily produce break, tired, the position that gets loose, be out of shape, therefore the adhesion strength with these two positions by discharge process increase is from silent utility model concept in this technical field institute.
In addition, confirm through inventor's test of many times result, the effect that discharge process is also adhered to for resin adsorption, glue line material or other functional aid is better, and therefore visual different demand and object are adjusted order and the number of times of its discharge process in overall process.
For example, such as, when horn vibrating reed needs further to add functional aid (dryingagent, incombustible agent etc.), when increasing the character such as its water-repellancy, difficult combustion/anti-flammability, can before interpolation functional aid, carry out discharge process, can effectively increase the combination of dryingagent, incombustible agent and horn vibrating reed, promote water-repellancy, the difficult combustion/anti-flammability of horn vibrating reed, to meet demand or the standard of car horn part, electronic installation inner body.
With reference to figure 8A, it shows the cutaway view of horn vibrating reed.As shown in the figure, comprise a cloth body 20 via the horn vibrating reed 200 of above-mentioned processing procedure manufacturing, it is woven and is formed (ginseng Fig. 5) by many warp thread 21 and weft yarn 22, cloth body 20 has a first surface 201 and second surface 202, and the first surface 201 of cloth body 20 and second surface 202 are combined with a resin bed 23 and glue-line 24.Because the fibrous of cloth body 20 is macromolecular material, its surface was nonpolar functional group originally, surface can be low, hydrophobicity is high, its surface (first surface 201 and/or second surface 202) is after discharge process, can make its surface (first surface 201 and/or second surface 202) coarse and form respectively a coarse polar surface 231, 232, except surface roughness increases, after discharge process, can make surface with a large amount of polar groups, make coarse polar surface 231, on 232, be easier to binding resin, glue line material, functional aid, solid etc., help material absorption or increase the then object of effect to reach.
With reference to figure 8B, it shows the cutaway view of horn vibrating reed.As shown in the figure, with Fig. 8 A similarly, can resist the physics/environmental factor under specified conditions in order to make horn vibrating reed 200, also can be after completing resin impregnated, glue-line and arranging further soaking function auxiliary agent (dryingagent, incombustible agent etc.), make horn vibrating reed 200 surfaces form a resistance layer 25 (can be drying layer or difficult combustion layer), make horn vibrating reed 200 can resist the physics/environmental factor under specified conditions, avoid the horn component causing because of these factors to damage.Particularly, because its surface roughness of the fiber cloth material through discharge process increases and with a large amount of polar groups, the also absorption of help function auxiliary agent, increases the effect that its drying/difficulty is fired.Horn vibrating reed 200 shown in this figure, the step of its soaking function auxiliary agent is after soaking liquid resin steps, but also functional aid can be added in liquid resin and carry out in the lump simultaneously.With regard to effect, the effect of separately processing is slightly good, but due to comparatively complicated on processing procedure, which kind of practice the characteristic of visual horn vibrating reed product requirement and the consideration of cost aspect, consider to adopt comparatively appropriate, is only to propose to illustrate at this, is not limited only to this.
As seen from the above embodiment; value in the true tool industry of the horn vibrating reed that the utility model specification provides and discharge process method of moulding thereof; but more than narration is only preferred embodiment explanation of the present utility model; all those skilled in the art are when doing other all improvement according to above-mentioned explanation, but these changes still belong in spirit of the present utility model and following defined scope of patent protection.
